中文摘要：

综述了近十年来过渡金属/分子筛催化剂上氨和碳氢化合物选择性催化还原NOx方面的研究进展。在NH3-SCR体系,着重介绍了铜基和铁基分子筛催化剂的研究状况,探讨了分子筛催化剂在该体系中的失活原因;在HC-SCR体系,总结了不同过渡金属、分子筛类型、还原剂、H2O和SO2等对催化剂活性的影响,探讨了目前比较公认的碳氢化合物选择性催化还原NOx的反应机理。最后展望了分子筛催化剂在选择性催化还原NOx领域今后的研究方向。

英文摘要：

A general review is given over the research advances in SCR of NOx with ammonia or hydrocarbons over transition metal-based zeolite catalysts in last 10 years.In NH3-SCR system,Cu and Fe based zeolite catalysts are particularly addressed,the deactivation reasons of these catalysts is discussed as well.In HC-SCR system,the effects of different metals,zeolite types,reducing agents,water vapor,sulfur dioxide on the activity of catalysts are summarized,and the well accepted reaction mechanism of HC-SCR is introduced.The future research directions for SCR over zeolite-based catalyst are also included.
